The “Out of Sundaland” migration model argues that the origin of the Austronesian speakers is in the islands of Southeast Asia. Ideal climatic conditions and natural resources for development were found in Sundaland. After migrating from the semi-deserted savannas of Africa, man first found a place where food was abundant and it was there that they invented farming, agriculture, trading and civilization, which made humanity first flourished. A striking thing that can be observed in this model is the dispersal of population to the other part of the world about 11,000 years ago. An unusual event was happened here.
The event is detected from the observation data. The change of the world temperature made the ice on the north pole to melt and the sea level continued to rise. Cracks in the earth’s crust as the weight of the ice shifted to the seas could set off catastrophic events.
The most significant one is at the end of the Younger Dryas period. Earthquakes, volcano eruptions, super waves and floods engulfed the coastal cultures and all the flat continental shelves of Sundaland, and wiped out many populations. As the sea rolled in, there was a mass migration of the survivors from the sinking continent.
From the legends, myths and tales, Sundaland has many names, among others are Garden of Eden, Paradise, Dilmun, Nippur, Nisir, Neserser, Ta Netjer, Land of Punt, Land of Ophir, Atlantis, Kumari Kandam, Pandya, Kangdez, Tollan and Siwan, Taprobana, and Golden Khersonese.
Plato mentioned that the island of Atlantis was beset, in a night and a day, by an earthquake and a flood in a night and a day, 9,000 years before Solon, or about 11,600 years ago. This accurately coincided with the cataclysm at the end of the Younger Dryas period. In some other his explanations, it is implied that the flood was coming from the sea, so the possibility is a tsunami. Plato did not recognize “tsunami” so he equated it to “flood”. Earthquakes and tsunamis are very often correlated.
